+// Manager class for TOF reconstruction.
+//
+//
+//-- Authors: Bologna-ITEP-Salerno Group
+//
+// Description: Manager class for TOF reconstruction (derived from TTask)
+// Summary of the main methods:
+// - extraction of the TPC (assumed to be) reconstructed tracks
+// comment: it has to me moved as soon as possible into a separate
+// class AliTOFTrackReader (K. Safarik suggestion)
+// - geometrical propagation of the above tracks till TOF detector
+// - matching of the tracks with the TOF signals
+//
+// Remark: the GEANT3.21 geometry is used during the geometrical propagation
+// of the tracks in order to know the current volume reached by the track.
